T0 ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, SAMUEL S. LAWS, ofthe city, county, and State of NewYork, have invented certain new and useful Improvements'in SignallingorIndicating-Apparatuses; 4and that the. following'description, taken inconnection with the accompanying'plate of drawings, hereinafter referredto,A forms a full and exact specification of the same, wherein I 'haveset forth the nature and principles of my said improvements, by which myinvention may be distinguished from all others 'of a similar class,together with such parts as I claim and desire to have secured to me byLetters. Patent. l

The present invention more particiilarly relates to an indicator orsignalizer described in the schedul annexed to the Letters Patentgranted to me on the thirty-iirst day of December, AL D. 1867, but theimprove ments embraced herein may be also adapted to other forms ofindicators or machines for conveying intelligence, by whatever force orpower operated; this class of indicators being intended for use moreespecially in showing or communicating the price of gold, stocks, bonds,produce, and other commodities disposed of and sold at thevarious'boards, or exchanges, and markets of our country and as atsiichboards and exchanges the variations of prices generally and by rule orcommon understandingiare by eighth;l u.use is made of this importantThis invention consists, first, in a novel transmitter and regulator ofmotion, which maybe termed a geared automatic advance and retrogrademotor and check; and this device consists of a peculiar method ofgearing together two or more wheels or arbors, or other devices,whereby, with a rotary or other motion imparted to the first one oftheseries, at a certain point or at points of its movement, an intermittentrotary orother movement will be imparted to-the next in the series,whether the first wheel has a continuous or an intermittent motion,while at all other times the second wheel,`without the use of anyadditional means, but from its own formland arrangement' with regardto-tl1e"`rst or actuating-wheel, will be stationary and fined inposition, and so`on through any number or series of wheels; second, inlocating either upon the periphery of a drum orwheel, or

upon the'ace of aldsk or plate, or upon any other suitable surface of adrum or wheel, or other device, arranged to have a rotary movement, orupon a stationary dial-i`ace or plate of any suitable shape, when suchdialface is provided with an index-hand or pointer, arranged to be movedaround upon its face from point to point, a complete series of thefractions of a unit, in eighths, from one to seven-cighths inclusive,viz, 1g, 85, 5, g, whether in regular order and succession or inirregular order, and whether either more or less duplicated, incombination with a full series of units of number,vfrom 0 to 9inclusive, upon the same or a different wheel, drum,A disk, dial-face,or other surface, whether such numbers are arranged in regular order orsuccession, or either more dr less in duplicate, or in combination withany'other series of characters, either more or less complete, Such/asthe `letters of' the alphabet, diphthongs, and other arbitrary orconventional signs or symbols for com munieating intelligence, Whetheruponthe same -or a different face or surface, or in combination withboth the units and the otheri'characters upon the same ora differentdisk or face, according as may be desired.

In the accompanying plates of drawings my improvements in reportingr orsignalling-apparatuses"are illustrated.

Figure 6, a. plan or top view'oi` a type-wheel; and

Figure 7, plate 4, is a vertical section, showing the working-apparatusof the machine, in which L and L represent two right and loft-handlevers, working on the pivots I and P', through the instrumentalities ofthe coils O and O, and the armatures R and lt. The operation of theselevers and, their appurtenances is substantially the same as the likecontrivanocs used in my patent for an electrical indicator, datedDecember 3l, 1857, and numbered 72,742.

A, i-n the drawings, represents a base or foundation-plate, on which theseveral parts constituting the apparatus are arranged. B, nprightssecured to plate A, along its sides, and carrying horizontal shafts C ClC, that at different points are extended across the plate A, turning ateach end in bearings of the nprights B.' These shafts, C C C2, in thepresent instance are three in number, and have secured to them similarcircular disks or plates, D Dl D2, respectively, the several disks beingvertical in position, and on the same side of the plate A, and arrangedin a position to lap over, the one upon the other.

0n two, D D, of these disks, are located, at equal and regular distancesapart, the series of units, from 0 to 9 inclusive, in regular andinverse order and succession; and on the remaining disk, D2, inconcentric circles,V as shown in the drawings, the letters of thealphabet, and other characters, the units of number, and the fractionalunits, (eighths.)

On the shaft C2 which carries the disk D2, and back ofthe said disk D2,by and through a geared or toothed wheel secured thereto, the mechanismprovided for operating the apparatus is to lie-arranged to act, one formand arrangement of which mechanism that may be used being that describedin the Letters Patent hereinbefore referred to, and therefore needing noparticular description herein.

E, a wheel fixed to shaft C2, and turning in conjunction therewith. Thiswheel, at one point of its periphery, is provided with a tooth, F, byand through which, as the wheel revolves, the wheely Gr, fixed tothenext shaft, C1, is revolved. This wheel G, around its periphery oredge, is divided into a series of concave faces, l'lf, ef equal length,and at equal and regular distances apart, with the several concave facesseparated by a notch or opening, I, of suitable shape to allow the toothF on the wheel E to enter as such wheel revolves, and acting upon itssides to move the whcelG. By the concave faces to the wheel G, suchwheel is always bearing upon the periphery of the Wheel E, and the curveof such concave faces is of a radius corresponding to that of the wheelon which it bears. I

Thus it will be seen, by the relative construction of the wheels E andG, and their arrangement, the wheel G will be revolved only when thetooth to the wheel E has become engaged with one of its notches orindentations, and for only a proportionate part of its circumference,when thc tooth escaping from tho notch, the wheel G, then, is at abearing by one of its concave faces upon the periphery ofthe wheel E,and consequently thereby held stationary or fixed, until, by the advanceor retrograde motion of -the wheel E, it is again carried back throughthe same, or forward through its next notch, and so on.

By this arrangement and manner of gearing, it is obvious that whatevermotion, whether continuous or intermittent, forward or backward, beimparted to thc vfirst or driving-wheel, E, the other or second wheel,G, will be correspondingly moved only at such times as the tooth to thedriving-wheeh by its movement, becomes engaged therewith, as described,while at all other times, by the concave face bearing upon thedriving-wheel, it is held stationary and fixed in position.

Wheels geared together as above described may be continued in a seriesof indefinite length, and in the present instance it is shown ascontinued to the next shaft, Cl, ofthe apparatus, by a wheel, L, havinga single tooth, M, on the shaft C1, and a concave or indented wheel, N,on the shaft C, when the operation between these two shafts will besimilar to that described between the shafts CZ and C1, as is obvious.

By my arrangement of gearing herein described, it is plainly apparentthat with the series of disks D Dl D2, having numbers and othercharacters upon them, as shown in the drawings, and with a caseenclosing the whole, having openings at such points as to expose onlyone character of any of the series of characters at one time, as shownby the 'red lines in iig. 1, around the characters, various and manycombinations of figures, letters, fractions, Ste., may be indicated orexposed to view, and such combination of figures, die., changed atpleasure in either one or more particulars, according to the informationdesired to be imparted.

On the disk D2, shown in fig. 1, the several letters of the alphabet,together with two diphthnngs, and other characters, are shown asarranged around in one and the same circle, and at regular distancesapart, the whole number of such characters corresponding to the teethupon the driving-wheel.

Upon a concentric circle within the alphabet circle are arranged theseveral fractions, from one-eighth to seven-eight'ns inclusive, with ablank space, making eighth divisions, or one division at every four uponthe Aalphabet circleg and upon a concentric circle within the fractioncircle are arranged the several units, from O to 9 inclusive, togetherwith other characters thereon shown, making sixteen in all, or two toevery division of tbe fraction circle.

With thirty-two teeth on the gear-wheel driving the shaft carrying thedisk CZ, by every movement of such wheel one tooth, a differentcharacter upon the outer or alphabet circle will be shown at the openingin the case provided for it, and when moved two teeth, a character uponthe inner or unit circle, and when moved four teeth, one of thefractions, Aat their respective openings.

In fig. 3 another arrangement of the fractional units is shown, inconnection with the letters ofthe alphabet, figures, and othercharacters. This arrangement consists in duplicating the fractions inthe manner shown, so that at the same time the price asked and bid canbe exhibited to View, inasmuch as the difference between the two isusually one-eighth, as thus shown.

In fig. 5, plate 3, in lieu of locating the letters of the alphabet,dto., upon a disk arranged to revolve, they' are located upon a fixeddial-plate in one and the same circle, around a common centre, whcreatan index-hand "faire 3 is secured to the driving-shatter arbor, so as tobe moved around the faceof the fixed dial. rlhis dial-plate is shown assecured to the outside of the case carrying the operating-mechanism, andalso two other disks around which the units of numbers and thelfractions are indicated, as shown in i'g., 54 of the drawings. And incon nection with the above a strip or band et paper is show n'as issuingfrom the box at one end.A On this strip, in the present instance, nrethe letters N. Y. C 1095i-, shown as printed.

To accomplish this, I intend to arrange the several fractions, units ofnumber, and othercharacters, around a type-Wheel, (see iig. 5,) to beoperated in a similar manner to that described for the disk ordiahplates, and, in connection with any suitable mechanism, onearrangement of which .is shown in fig. 4, take impressions therefrom atthe proper times upon the strip before referred te.

' This arrangement of mechanism forms no part et' the presentimprovements, but-is to be made by me the subject of a separateapplication hereafter.- There are, however, other arrangements which maybe used for the purpose, and therefore I do not deem it necessary toherein any more particularly refer to it. r.

dt will be seen by reference to the drawings and description in thiscase, ythat the instrument described is peculiarly adapted to reportingthe movements ofv gold or stocks atany financial centre. Therigi'it-i'iand disk has a unit, divided -into cighths, to correspondwith the smallest subdivisions by which stocks adva'nce or recedeiniprieti'e'e. 'Ihe arrangement ofthe several disks permits theiiguresand fractions which communicate `the intended intelligence toassume a position in a horizontal row, and to appearvthrough apertures,asshown in tig. 5, plate 3, or to be seenthrough a single, straight,elongated aperture', similarly arranged, or in any other position thatmay be desired;

I am aware that a series-of Wheels has been alternately moved and heidinplaceupon the same principle as is hereinbei'ore described. I amalsoaware that a right and left-hand seapement-m`ovement has been used tomove a ratchet-Wheel backwards or forwards by means ot'electro-magnetism; therefore, neither o' these contrivances is claimedby itself, but i I i What I do claim as my invention, and desire tosecure by Letters Patent in a reporting and signallingapparatus, is

1. A series ot' wheels thus alternately moved and held in check, incombination with contrivanees for giving either an advance or aretrograde movement, 'according to circumstances, substantially in themanner and for the purpose above set forth.

2. In a reporting and signalling-apparatus, I claim the series ot'dislts and wheels, as above shown, in cornbination with the coils O' 0,the armatures R R', and the leversA L L', constructed, arranged, .andoperating substantially as above sot forth. 'i

3. In areporting and signalling-apparatus, intended specially to reportthe rise and fall of gold, stocks, Bte., I claim the use ofdisks'operated substantially as above shown,` and so arranged as tepresent integers representing tens, hundreds, 8vo., as well as fractionsvarying by eighths, when the whole are so disposed, either in rows or inany other pre-arranged order, as to communicate at a glance the changesin the stock-market, sul",-

stantially in the manner above described.
